Treatment of enantiemerically enriched epoxy mesylates 7-9 with potassium alkoxides under carefully controlled reaction conditions (18-crown-6, THF, -78°C) provide the coresponding α-alkoxyketones 10-13 without significant racemisation. The reactions are shown to proceed with net stereochemicaI inversion at the epoxide centre.
